Salazar,

There is no resistance to horizontal motion. The motion will be constant. The time taken will be proportional to the distance travelled.

How are the periods numbered?

Simply put from my time in early schooldays, teachers said they grouped elements together which had things in common. Technically, see the following,

From what I've seen, it is very stable when damp. Use acetone, not water. Why can't you screw around with something less sensitive, like tatp, or plain gunpowder?

I don't intend to use this chemical, the main point was that it appeared easily in a list on a google search.

I watched the video a few times and I noticed the possibly important word " dry " being used. Not that I want to know very much of the theory of nitrogen triiodide but is it stable when it is put on the paper mixed with a solvent and what we see in the video is the dried chemical without the solvent being given a tiny impact?

Anyone who wants to can Google nitrogen triiodide and find out how to make it. They are not very likely to come across this page.

However it's possible that someone will be interested in ammonium fluoride melts and find this page. If it tells then to be careful about adding halogens to the mix then it's beneficial.

I googled nitrogen triiodide and near the top was this.

Dangerous sh*t, how was it put on the paper if it is so sensitive to a feather?

In some thoughts, , what else is disappearing slowly?, in others, , that's really interesting!

Is the boot slowly being eaten?

This is my old leather boot. It's been sitting undisturbed for at least 5 years in the garden shed, that's how long I've been looking for it, now I've found it.

It looks like it's all there, there is no major wearing away of it. But, it has a white substance on it that powders easily when it's scraped off.

There isn't very much of it, it's light and floats away in the wind quite quickly. Any ideas what it might be?

 

It will give a couple of volts or so which makes the energy available about

21 MJ

About 6000 KwHr

 

21 MJ would make about 6 KiloWattHour

21 GJ would make about 6000 KiloWattHour

For the benefit of everybody having a read here , how much electricity are you trying to make ? 1 microwatt second or 100 megawatt hours ?

Take your aluminium and make a heat collector which basically will sit in the sun and heat up. Use the fact that you will then have a big lump of hot metal as a source of heat to make electricity.

Solar flat plate collectors ?

Burn it .

Remind me to use a pinhole camera next time I'm bugging a room.

Here is your reminder John !

The assumption is of an ideal gas.

Do you know any of the forms of the ideal gas formula in SI units ? There are a few which can be used based on the information you have and the information you want to get.

Do you know the pressure in the tyre in SI units ? ..................................... N / ( M^2 ) ...................................... Newton per square Metre

Do you know the volume of air in the tyre in SI units ? ................................................. ( M^3 ) ............................................ Cubic Metre

Do you know the temperature of the air in the tyre in SI units ? ................................................... K ............................................ Kelvin

Do you know the specific gas constant for air in SI units ?

Thus Calculate the mass in Kilograms !

The United States of America is a Republic of the people , for the people. If the peoples' Republic provides for the people in the form of socialism by taking from those who have to give to those who have not then the Republic has won for it's people.

Please, I am in need of help. I'm having difficulty in answering this question: "Two tugboats towing a barge exert a force of 5.0 N each. If the angle between two ropes is 30 degrees, what is the resultant force exerted on the barge?"

 

Anyone willing to help me with this + showing it thru graphing?

Why is there a presumption of mistaken forces ? The original poster asks a question with two forces each of 5.0N, two 5.0N forces applied to a small floating model in a classroom at an elementary level could be quite understandable.

If you would like to run down to the patent office, have it in mind, if I am not mistaken, that rules say that you can't patent an invention that has already been made public. Maybe this doesn't apply in your country.

My browser is being really stubborn right now, so I can't watch the video. You'd need to post a link for me to say anything for sure.

Perfect separation is the goal. For example , an amount extracted which is a high percentage of one salt and a low percentage of the other is not the goal. Total purity of extraction is the goal. Industrially there are expensive machines that do a good job of giving a high purity of one or the other salt. Simple tools in a kitchen is difficult.

It is extremely important for clarity that the meaning of resistance is understood in it's true meaning as either inside of or outside of a circuit or both , whichever case is applicable.

I'll assume that John Cuthber and WHR both have electrical knowledge and it is quite interesting that the meaning of a fundamental such as resistance is being questioned. Is a term such as Potential Resistance / Static Resistance useful as opposed to Actual Resistance / Dynamic Resistance. Invent a compromise!

If the self same stone as earlier was dropped from a very high building and collided with the pavement as previously, would any electron from the stone swap it's orbit for a new orbit around a pavement nucleus or vice versa?

So, elfmotat, assuming electrons have no volume but have mass, is the nucleus likewise? I do hope you have a mainstream accepted view of this type of thing.

Does the Bible describe Jesus Christ as ever making a totally new scientific discovery? Surely a person like him must have been the first to explain a phenomena that nobody could understand.

Electrons do not have a 3D shape.

Could you elaborate?
